TIE-PLATE FORBRUSH-FILLINGS.

SPECIFICATION forming part of Letters Patent No. 431,770, dated July 8,1890. Application filed May 7, 1889. Renewed June 12, 1890. Serial No.355,149. (No specimens.)

To all whom/it may concern.-

Be it known that I, SAMUEL K. HAwIgINs,

of Elmira, in the county of Chemung and State of New York, have inventeda new and useful Improvement in Tie-Plates for Brush= The inventionconsists in the novel construct-ion ofthe plate and in the combinationof said plate with the brush block and filling, as will be hereinaftermore fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

in which' similar figures of reference indicate.

corresponding parts in all the views.

Figure 1' is an end view of a brush having my improved plate appliedthereto. Fig. 2 is a side elevation of the same. Fig. 3 is a transversesection through the plate and a partial longitudinal section through thebrush head and filling. Fig.4 is a perspective view 0 of a detachedplate, and Fig. 5 is a transverse section of the brush.

The brush 10, to which the plate is especially applicable, consists of ablock 11, provided with a series of longitudinal grooves 12 3 5 in theunder face, in which grooves filling 13, of any desired character, isinserted to serve in the capacity of bristles, which filling isordinarily held within the grooves by a wire rod 14, over which thefilling is bent, which rod is secured in any approved manner at or nearthe ends of the block.

In securing the filling into the brush-block it is especially desirablethat the said filling at the end of each row shall project beyond theend of the brush-block, as best shown at 15 in Figs. 2 and 3, in orderthat the brush may be used effectively to clean any surface in thecorners, for instancewithout the end of the brush being brought inunpleasant contact with the walls. In order to permit of thisconstruction and protect the upper exposed ends of the filling,I'provide a plate 16,

illustrated in detail in Fig. 4, the general contour of which plate 16is made to correspond, preferably, with the end contour of the brush- 55 block 11", at which point the plate is adapted to be secured by nails,screws, staples, or equivalent fastening devices.

The inner face of the plate is indented or otherwise manipulated to formrecesses 17,

'by means of which operation, if the plate is thin, the correspondingoffsets will be produced upon the upper face of the plate, asillustrated in Figs. 1 and 2. The recesses 17 are so located in theplate that when the plates are seen red to the ends of the brushblock 11one recess will be immediately opposite the end of each row of filling,as shown in Fig. 3, the projection of the filling beyond the end of thebrush-block being regulated by the depth of the recesses.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. As a new-article of manufacture, an end tie-platefor brush-fillings having a recessed inner face, substantially as shownand described.

2. As a new article of manufacture, an end tie-plate for brush-fillingsprovided with a series of indentures or recesses in the inner face, asand for the purpose specified.

3. As an improved article of manufacture, an end tie-plate forbrush-fillings provided with recesses in the inner face, wherebycorresponding offsets are produced upon the outer face, substantially asand for the purpose specified.

4. The combination,with a brush-block, and filling secured in the saidbrush-block in 0 rows, the ends of which rows project beyond the endsurface of the block, of a tie-plate secured to the ends of the saidblock and provided with recesses in the inner face corresponding innumber with the rows of filling and registering with the ends of therows of the said filling, substantially as shown and described.
